I was a big fan and as I have added to the devices it has become harder to install. The app and the Arc keep forgetting each other and have to go thru a list of questions that show me the Arc then it says not found. The iPhone app does not stay active when the screen times out. Have to log back on the iPhone to mute or unmute it is just easier to use the TV controller. The Arc can not be controlled by the Virgin controller. I will not be buying any more Sonos devices as the whole system has become cumbersome and slow and unreliable.
Even registration for this forum asks questions which I answered but the username was not unique and I had to answer them again and then again because I did not acknowledge the terms. It seems unlikely that any of my choices would have changed I. The 5 seconds between attempts. Do they not test S2 and the registration process with real users.
